3M 7000144554 Diamond Lapping Film Disc 4 Inch Psa

Product Description

The 3M 7000144554 is a PSA-backed diamond lapping film disc designed for precision surface finishing on extremely hard materials. Built on a stable polyester film substrate, precisely graded diamond abrasive particles deliver a consistent, repeatable finish pass after pass. The pressure-sensitive adhesive backing allows fast disc changes on compatible backing plates, reducing downtime during high-throughput lapping operations. This disc measures 4 inches in diameter and is suited for applications requiring tight surface finish control across a broad range of micron grades from 0.10 to 30.0 micron.

This lapping disc is used in precision finishing operations across optics, ceramics, carbide tooling, and other extremely hard substrate applications. It is well suited for achieving flat surfaces with low edge rounding, making it a common choice in metrology labs, tool and die shops, and fiber optic connector finishing environments. The PSA backing is compatible with standard lapping plates and rotary disc tools that accept adhesive-mount abrasives. Minimum order quantity is 50 discs per order.

Key Features

• PSA backing for fast, secure disc mounting and quick changeovers
• Precisely graded diamond particles on a dimensionally stable polyester film
• Delivers flat surfaces with low edge rounding for tight-tolerance finishing
• Consistent, repeatable finish across the full abrasive life of the disc
• Available in grades from 0.10 to 30.0 micron to match a wide range of finish requirements
• Long abrasive life reduces the frequency of disc changes and improves throughput

Compatibility

Designed for use with standard PSA-compatible lapping plates and rotary disc finishing tools that accept 4-inch adhesive-backed abrasive discs.

Installation Notes

Installation is performed by surface finishing technicians and precision machining professionals. Before mounting, ensure the backing plate surface is clean and free of debris to achieve full PSA adhesion and a flat working surface. Apply firm, even pressure across the disc when adhering to prevent air pockets. Follow equipment manufacturer guidelines for disc speed and coolant or lubricant use when working with diamond abrasives on hard substrates.
